Difference between food grade stainless steel pipe and sanitary grade stainless steel pipe

In most cases, there is no clear distinction between food grade and sanitary grade products. Generally (not necessarily) one of the requirements can be met, and the other can be met. The reason why it is divided into food grade and sanitary grade is that the direction of certification (standard source) is different. Strictly speaking, there is no food grade or hygiene grade at all, which is just the customary name of people for whether materials and products meet certain use requirements (not manufacturing standards).

In China, it refers to materials and products that can meet the national health related standards and national food related standards when used, which can be called health grade and food grade. For example, if a certain type of plastic raw material can be used as food packaging materials after being inspected and confirmed by the food supervision department, it can be said that the type of plastic has reached food grade; The same material can be made into medical devices after being inspected and confirmed by the health supervision department, so it can be said that the plastic of this model has reached the hygiene level.
